Kindred Spirits

From The World Ends With You - Wiki on Neoseeker

The Kindred Spirits are a group that comes together in Another Day in order to get their stolen pins back from the Black Skullers.

The Kindred Spirts consist of Neku, Shooter, Beat, Joshua and Shiki. Rhyme also joins the spirits for a little while, although she turns out to be a spy for the Black Skullers. The Kindred Spirits also use color names for all their members, with Neku switches between black&blue, then being brown&blue, before finally settling on Blue. Shooter is Red, Shiki is Green, Joshua is first pink, switches to gold for about an eighth of a cutscene, before being Pink again. Joshua switches to Rainbow later on in the story. Beat is Yellow, and Rhyme is Black for the short time she is with them.
